Main propulsion arrangement and power generation concepts

Abstract

An overview is given of mechanical, electrical and hybrid propulsion arrangements. The relation between propulsion concepts and power generation is explained and elaborated in energy flow diagrams. A general procedure for analyzing propulsion and power generation concepts is presented, using energy conversion effectiveness and based upon a selection of operational modes and a mission profile reflecting the use of those modes. Potential matching problems when switching between propulsion modes are identified and possible solutions given.
